SPADLOCK.

Application filed December 17, 1925. Serial No. 75,898.

rlhis invention relates to locks; it has forV one of the legs of the shackle, the inner endl of said barrel being constructed so that when it is in unlocked position said shackle may move outward relative to said body vand is prevented from complete removal from said body by a detent on said barrel which engages with an abutment near the inner end of said leg, but when said shackle is in inward position and said barrelis rotated to locked position the inner edge .thereof will enter a lockingrecess provided inV said leg for locking the shackle in such position.

Other and further important objects of this invention will be'apparent from the disclosures in the specification and the accompanying drawings.

This 'invention (in a Ypreferred form) is illustrated in the drawings Vand hereinafter more fully described. Y 4

On the drawings:

Figure'l represents an elevational view of a padlock embodying this invention;

Fig. 2 is an enlarged vertical section of the padlock showing parts in elevation;

Fig. 3 is a sectional view taken at the line III-HI of Figure 2 with parts omitted;

Fig. 4 is an enlarged fragmentary detail view of a section at the line IV-IV of Figure 2 with parts omitted and showing the lock barrel in elevation; and

Fig. 5 is a fragmentary vert-ical sectional view of a padlock ,showing a modified form of the invention.

As shown on the drawings:

Numeral 1 represents the body portion of the padlock. The body 1 is of substantially ball shape to permit the same to be more easily polished and to afford a maximum of strength especially in this particular form of'lock wherein a pair of parallel cylindrical recesses 2 and 8 are provided in said body for slidably holding legs 4 and 5 respectively of a shackle 6 and wherein a third cylindrical recess 7 is provided in said body for rotatably containinga lock barrel 8, the axis of which is disposed at an acute angle to the leg 4. A locking cylinder 9 surrounds the barrel 8 and is rigidly contained within an enlarged portion 10 at the outer end of the recess 7 A key 11 mav be used to unlock the b arrel 8 from the cylinder 9 and cause rotation of said barrel to or from locked position as will be hereinafter described.

A locking 'recess 12 is cut in the side of the leg 4 near the inner end thereof for receiving therein the 'lower inner edge of the barrel 8. The provision of the recess 12 affords a shoulder 13 in the leg 4 which is adapted to be engaged by the inner edge of the barrel 8 for locking the shackle'6' in the body 1. A longitudinal groove 14 extends from the recess 12 to an annular` transverse'groove 15 adlacent the inner end of the leg 4. The provision of the groove 15 affords an annular transverse shoulder 16 for a purpose that will be apparent hereinafter, There isvprovided in the inner edge of the barrel 8.a recess 17,

tric with the side of the leg 4 when the Vbarrel is in unlocked position withxthe eXceptionfof an irregular portion'at the right of said recess for the provision ofa lug or detent 18 formed from said edge and extending into said recess. When the barrel 8 is moved to unlocked position the recess 17 will permit the leg 4 and the shackle 6 including the saine -tobe drawn outwardly. Thelug 18 will engage in the groove 144 during 'the outward movement of the shackle 6 and thereafter will enter the annular groove 15 and by engagement with the shoulder 16 therein will prevent complete removal of said shackle but will permit rotation thereof in the body 1.

The inner edge of the barrel 8 is provided with a beveled portion 19 to the left of the recess 17 for permitting said 'edge to extend as far as possible into the recess l2 in the leg 4. A peripheral groove 2O is provided near the inner end of the barrel 8 in which extends ascrew 21 secured in the body 1 from the bottom of the recess 8.

In the modification shown in Figure 5, there is shown a similar device in which provision is 'made for locking both legs of the shackle. A recess 22 is provided in the shorter leg 5L of the shackle and an additional revthe bottom of which is substantially concensaid recess23. When the lock barrel is rotated from unlockedposition the ball 25 will be ejected from recess 23 into the passage 24 llU and, if the leg 5a is in locked position, partly into the recess 22 to thereby act as a detent and thus lock said leg.

I am aware that many changes may be made and numerous details of construction may be varied through a Wide range Without departing from the principles of this invention and I therefore do not purpose limiting the patent granted hereon otheWi'se than necessitated by the prior art. o

I claim:

l. A padlock including a lock body, a shackle including'a pair of legs slidable in said body to and from locked position, a lock barrel 'rotatable in vsaid body to and -from locked position, the axis of said'lock being positioned at an acute angle to said shackle, one of the legsof said shackle having a locking recess therein, the inner edge of said barrel being adapted to enter' said recess when in locked position and having a recessk therein for permitting movement of said leg thereby when said barrel is in unlocked position, and a detent associated With said barrel and operable bythe rotation thereof to lock the other of said legs Whensaid barred is rotated to locked position. Y Y

'2. A padlock including a flock body, a shackle including a pair of legs slidable in said body to and from lockedposition, a lock barrel rotatable in said .body to and from locked position, one of the legs of said shackle havinga locking recess therein, the inner edge of said barrel beingl adapted to enter said recess When inA locked position and having a recess therein for permitting movement of said leg thereby When said barrel 1s 1n unlocked position, land a detent `normally received in said barrel and ejectable therefrom' for locking the other of said legs When said barrel is in locked position.

- 3. In a padlock, a lock body, a shackle s1idable in said body, one of the legs of said shackle having a recess therein, a lock barrel having a recess therein and rotatable in said body and engage'able in said recess, means to pre- Vent'the removal of said shackle from said body, and means normally in a -recess in said lock barrel and expellable therefrom to lock the other of said legs against removal from said body.

'4. In apadlock, a lock body, a shackle including'legs slidable in said body, said legs each having a recess therein, a lock barrel rotatable in said body and engageable in one of said recesses to prevent slidable movement of said shackle, said barrel having` a recess therein, a movable member associated With said last mentioned recess and engageable With the other of said first mentioned recesses When said barrel is in locked position.

5. In a padlock, a lock body, a shackle including a pair of legs slidable in, said body,

each of said legs having a recess therein, a lock barrel having a recess therein and rotatable in said bodyV and engageable in the recess in one of said legs When in locked position, and means normally receivable in the -recess in said barrel and ejectable by the rotation thereof into engagement With the recess in the other of said legs.

In testimony whereof Ihave hereunto sub- 'scribedmy name. Y
